IPC: B23K7/10
Filed: 1958-06-28
Abstract: 881,121. Automatic position control systems. SCHICHAU G.m.b.H., F. June 28, 1958, No. 20803/58. Class 38 (4). [Also in Group XXII] In an automatic control device for controlling the spacing between a tool head and a workpiece, such as a pattern or template controlled flame-cutting or welding machine, the height h of the tool head 1 above the workpiece is maintained substantially constant by feelers 3, 4, 5, 6. A flame-cutting machine has its burner 1 rotated about a vertical axis x-x through gearing 27 by mechanism controlled from the pattern. Feelers 3, 5 and 4, 6 respectively are mounted for tilting movement against the restraint of strong biasing springs 21, 22 on devices 10, 9 whereby any tilting movement caused by engaging an obstruction closes a contact D, Fig. 3, which acts through relay D<SP>1</SP> and produces rapid acceleration of a motor 34 to raise the head. To compensate for gradual changes in height of the workpiece, both devices 9, 10 are mounted on a bell-crank lever 7 pivoted on a horizontal knife edge 8. This lever moves easily in response to vertical movements of the feelers and carries a cam 14 which actuates either a contact A to produce upward movement of the head or a contact B to produce downward movement; both contacts energize the motor 34 through relays A<SP>1</SP>, B<SP>1</SP>, respectively. Excessive downward movement of the feelers closes a contact C which stops the motor 34. The feelers may alternatively be mounted in a vertical guide.

Title: Art of refining hydrocarbon oils
IPC: C10G21/20
Filed: 1932-07-26
Abstract: <PICT:0390697/III/1> Petroleum lubricating-oils are refined by treating with nitrobenzene and sulphuric acid simultaneously. Preferably the oils are given a number of successive treatments, the used mixtures from the later treatments, with or without added nitrobenzene or/and sulphuric acid being used in the earlier treatments.  Separation of the treated oil from sludge may be facilitated by mixing say 5 per cent of sodium sulphate with the acid, or by adding water to the treated mixture.  The oil may first be dewaxed and/or subjected to mildly oxidizing conditions, e.g. treatment with ozone, and it may finally be neutralized, e.g. by caustic soda, lime, or ammonia, and/or treated with or filtered through an absorbent earth such as Olmstead earth.  Suitable conditions and proportions are 45-100 DEG  F. for 60-3 minutes with 50-400 per cent by vol. of nitrobenzene and 0,1-10 lb. of acid per barrel of oil.  With the apparatus shown the oil is treated four times.  Oil from tank 1, acid from a blow-case 4, and nitrobenzene from a tank 5, or sludge containing nitrobenzene from a tank 6 are mixed in a tank 2 containing a heating or cooling coil 7, and are pumped to a settling tank 8 or 9 containing a coil 10 or 11.  The sludge is discharged to a tank 12; the oil to a tank 14 in which it is thrice mixed with and separated from nitrobenzene and sulphuric acid or sludge containing them, the sludges being pumped respectively to tanks 12, 6, 16.  The treated oil is pumped to a stock tank 17, and supplied therefrom to a jacketed tank 18 in which it is agitated for 5 mins. at 150 DEG  F. with 5 per cent of Olmstead earth from a hopper 20; the mixture is pumped through a filter press 22, and the oil passed to a stock tank 24, and thence to a still 28 in which residual nitrobenzene is removed by steam.  This recovered nitrobenzene is pumped to the tank 5; the oil is pumped through a filter 29 or 30 containing Olmstead earth, or is mixed with 5 per cent of Olmstead earth and maintained at 400-500 DEG  F. for 30 mins., and is then passed to a stock tank 32.  Nitrobenzene is recovered from the sludge in the tank 12 by neutralizing in an agitator 33 with lime from a hopper 35, and distilling with steam in a still 36.  The nitrobenzene is returned to the tank 5; the still residue is passed to a tank 42 and is reduced to coke in a still 39, the distillate being pumped to a tank 40, and afterwards cracked to gasoline of high antiknock value.

Filed: 1923-08-20
Abstract: 224,952. Frankland, E. Aug. 20, 1923. Laminar springs; fluid-friction vibration-dampers. - A spring suspension for a motor vehicle comprises a primary spring supporting the frame on the axle and a secondary spring mounted to float on the frame under normal load conditions but yieldingly interconnected to the frame and axle by means which, when the frame moves downwards relatively to the axle, establish the secondary spring in engagement to resist such movement. The primary spring 3, clamped to the axle in the usual way, is connected at its ends to the frame 1 by shackles 5, 6, a radius rod 9 being provided to restrain the axle. The secondary spring 10 connected at its front end to the frame by a shackle 14 is mounted at its centre on a plate 12 carried by a shackle 13 connected to the primary spring shackle, its rear end being connected to links 16 pivoted to the primary spring at 18 and connected at 21 to the rod 22 of a piston 24 working in a dash-pot cylinder 1 secured to the frame 1. The rod 22 is ball-jointed to the piston 24, as shown in Fig. 3. When the frame descends relatively to the axle the engagement of the piston with the cylinder head brings the secondary spring into action as a load support, while rebound of the frame upwardly induces a vacuum in the cylinder exerting a lifting stress on the piston rod which is resisted by the secondary spring.
